Abstract: In current years, an attention on a world level
have achieved by Wireless Sensor Networks. These consist of small sensors with limited resources and limited power. Wireless sensor standards developed with the special need for consuming low power. The effectiveness of WPAN (Wireless Personal Area Network) with low-cost communication is improved by Zigbee. In this paper we discuss about wireless sensor networks, Zigbee technology, topologies.
Key Words: Zigbee Technology, Wireless Sensor Network. 1. INTRODUCTION
Function Devices (FFD's) is found in the web, and these devices bolster all the 802.15.4 functions. They can serve as network routers, network coordinators, or as devices that interact with the physical cosmos. The Reduced Function Device (RFD) is the last device found in these networks, which normally and only serve as device that interact with the physical world. Zigbee supports several topologies like star, cluster tree, and mesh. A new technology Zigbee is now being deployed for wireless sensor networks. A sensor network that allow the administrator to instrument, watch over and react to events and phenomena in a specified environment, is an infrastructure composed of sensing, computing and communication elements.
Wireless Sensor Networks (WSNs) consists of multiple sensor nodes that sense environmental phenomena and generate sensor readings that are forked over, typically, through multi-hop paths, to a specific node (called the sink node) for collection.

Fig 1: Wireless Sensor Networks Zigbee is the most popular industry wireless mesh networking standard for linking sensors, instrumentation and control systems. Zigbee is known as the "Internet of things", is a specification for communication in a Wireless Personal Area Network (WPAN). Theoretically, Zigbeeenabled coffee maker can communicate with a Zigbeeenabled toaster. Zigbee is a global, open, packet-based protocol designed to offer an easy-to-use architecture for a reliable, safe, low power wireless networks. Zigbee devices intercommunicate with one another by using the digital radios. A typical Zigbee network consists of several types of gimmicks. Every Zigbee network must include a network coordinator. A network coordinator knows about every one of the nodes inside its network, and oversees both the information about every node and also the data that receives/transmits within the network. Every Zigbee network consists of a network coordinator. Other Full Š 2018, IRJET

Zigbee is based on IEEE 802.15.4 Standard with capacity coordinating mutual communication among thousands of tiny sensors is a new wireless communication technology with short length, low complexity, low energy consumption, slow data rate and low-cost. The sensors can send the data from single sensor to another with small energy cost and high-efficiency through the radio waves. Zigbee technology has the lowest energy consumption and price when compared with various existing wireless communication technologies. Zigbee technology is extremely suited for agricultural field which has a small amount of data flows because of the slow data rate and the small range of communication. Zigbee makes it as the best choice for the wireless sensor networks because of the technical characteristics in its technology. Hence, it has the practical significance when applied in the crop environmental monitoring system. ISO 9001:2008 Certified Journal
